adding 26 to PYTHON_VERSIONS_ACCEPTED

could we add add 26 to PYTHON_VERSIONS_ACCEPTED where appropiate ?
This way an additional python < 2.6 would not be build, when
PYTHON_VERSION_DEFAULT is set to 26.
For example:
net/youtube-dl
sysutils/py-dbus
textproc/gnome-doc-utils
textproc/py-docutils
zafer.
